5pcs N35 40x10x3mm Strong Block Magnets Rare Earth Neodymium Magnets

Description:5pcs N35 40x10x3mm Strong Block Magnets Rare Earth Neodymium MagnetsNeodymium (chemical symbol Nd) is element 60 on the periodic table. It is a rare earth metal and forms one of the Lanthanides series. When added to Iron (Fe) and Boron (B) (chemical formula Nd14Fe21B) the resultant magnets are the strongest magnets currently available.Neodymium magnets are sometimes known as Neo, Neod or NIB magnets.Neodymium magnets are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting.Neodymium block magnet was made of NdFeB, have strong magnetic performances and appearance does not rust, usually placed in room temperature, the maximum operating temperature is 80 C , and it never will demagnetization.Specification:Shape: CuboidMaterial: NdFeBPlating: Ni-Cu-Ni ( Nickel )Grade : N35Operating temperature: 80℃Size: 40x10x3mmForce: approx. 2kgGauss: 2800Quantity: 5pcsNote:1.Please allow 1-3mm error due to manual measurement.Pls make sure you do not mind before you bid.2.The color may have different as the difference display,pls understand.Applications:Acoustic Field: the speaker, receiver, microphone, alarm, stage audio, car audio and so on.Electronics: permanent magnetic actuator vacuum circuit breakers, magnetic relays, meter, meter, sound meter, a reed switch, sensors.Electrical Field: VCM, CD / DVD-ROM, generators, motors, servo motors, micro-motors, motors, vibration motors.Machinery and Equipment: magnetic separation, magnetic machinery.Healthcare: me
